Oxyfern

Oxyfern is a non reproducing plant that absorbs and exudes breathable   (the rate seems to change, probably related to the air pressure).

Ratios
The s have quite similar gas conversion rates to the Duplicants, however they are ~3.2 times slower, and produce slightly more than duplicants consume, which makes it impossible to cleanly match their number to the number of duplicants, leading to either Oxygen or CO2 runaway overproduction.

Domesticated s convert ~98% of to, which is still 10% more water-efficient than  (88%  to ), with the additional cost of 4 kg/cycle.

As with any other plant, wild s produce 4 times slower compared to domesticated ones, however they do not require water or dirt.

Growth
requires temperature range of 0 °C to 40 °C. It requires air pressure of 25 g to 10 kg. It requires Carbon Dioxide atmosphere.

has no growth cycle.

Domestic
An can be planted in a,  and.

A domestic requires 4 kg/cycle  and irrigation of 19 kg/cycle.

Tips

 * Note how high their pressure range is; unchecked oxygen or carbon dioxide production might eventually overpressure your colony.
 * The is sometimes offered as a Care Package. There is no other way to increase amount of Oxyferns on the map.
